Using twist 3 contributions and the relations, which emanate from the QCD equations of motion, we derive the gauge invariant amplitude for the deeply virtual Compton scattering (DVCS) off hadron with an arbitrary spin. We emphasize that our derivation is not based on a certain parametrization of the relevant hadron matrix elements of the quark(gluon) operators. As an application, we present the gauge invariant amplitude for the DVCS off spin-one hadron. Using the derived gauge invariant amplitude, the single spin asymmetry is discussed.

  1. Deuteron gravitational form factors, generalized parton distributions, and charge density in the framework of the soft-wall AdS/QCD model

    The deuteron is modeled as a twist-6 vector field in thermal soft-wall AdS/QCD, yielding gravitational form factors, GPDs, and charge densities whose temperature dependence is governed by a modified dilaton parameter.
